Jake, 12, who has raised £600,000 for sick children despite battling leukaemia, took to the role like a duck to water on a visit to 10 Downing Street.

Pride of Britain winner Jake Peach sat in the Prime Minister's chair yesterday and declared his next ambition was to run the country.

Jake, 12, who has raised £600,000 for sick children despite battling leukaemia, took to the role like a duck to water on a visit to 10 Downing Street.

Millions of TV viewers will see Jake win over a host of celebrities tonight as he cheekily picks out Frank Lampard from the crowd and demands he donate cash.

And yesterday, he turned on the charm to win over Gordon Brown too.

Jake clutched his Child of Courage award as he confidently chatted to the PM about his incredible fundraising efforts for Great Ormond Street hospital in London.

Mr and Mrs Brown have been in and out of hospital with their son Fraser, three, who suffers from cystic fibrosis, and expressed great admiration for his cause.

The PM told Jake: "We spend a lot of time there. It's an amazing place. We try to help them as well." He also pressed football-mad Jake to follow up on the bet made with Chelsea star Lampard. He said: "If Arsenal beat Chelsea, Lampard's going to give a big donation, is that right?"

Jake and the other Pride of Britain winners were guests of honour at No.10, sipping coffee with the PM and wife Sarah after the 11th star-studded awards night. Mr Brown gave the heroes a tour of the rooms and they even got to try out Mr Brown's chair in the Cabinet room.

Jake, from Southend, Essex, admitted he was "overwhelmed" by the visit but showed no nerves as he chatted to the PM.

He told him: "I had a really late night. I was up till 2am. I was overwhelmed and hardly slept. And this morning I feel overwhelmed all over again." Among those Jake met at the awards were Esther Rantzen, who he described as a "very nice lady".

He added: "Joe Calzaghe was really nice. Is he English? He's got a bit of a funny accent hasn't he? He's Welsh? Oh that makes sense. And Frank Lampard was just absolutely brilliant. He was really good with me. I made a bet with him. He said if Arsenal win when they play Chelsea he'll make a donation. He said Phillip Schofield was one of his favourites too.

"He took time out to talk to me when he was really busy," Jake said.

Jasvinder Sanghera, who campaigns to free people from forced marriages, said the tour inspired her. She said: "When I sat at the Cabinet table I thought, I'm going to come back one day. I'm going to be one of the people making decisions."

And Chris Saunders, 33, the winner of the Prince's Trust young achiever award, reflected on the events that have led from him sitting in jail five years ago to being at the Cabinet table after running a drug counselling centre.

He said: "I could never have imagined this back when I was in prison, it's so far beyond my comprehension of what was possible I feel like it's a dream.

"It was the place where Churchill did his speeches during the war - and now I'm here! It really makes me want to keep going, to keep helping addicts."

Teacher of the Year Jonathan Heeley, 40, who proved an amazing hit with his maths rapping, said: "Being in Gordon Brown's home today is surreal. It's a real buzz being in the Cabinet room as well."

He said he was desperate to get back to his Huddersfield classroom.

ITV Feelgood Factor winner Andy Dalby-Welsh said: "I was blown away by it last night. Being here today is even more mind blowing."

And local champion winner Eunice McGhie-Belgrave said: "This is an opportunity I didn't think I would ever receive. I have so many lovely stories to tell the grandchildren."
